CD4015BCN dual 4-stage static shift register ic
The CD4015BCN is a versatile and reliable dual 4-stage static shift register integrated circuit from the standard 4000-series CMOS logic family, designed for serial-in, parallel-out data handling. It consists of two identical, independent 4-bit shift registers, each with a data input, a clock input, a reset input, and four parallel outputs, enabling flexible data storage and transfer operations. Operating from a wide supply voltage range of 3V to 15V, it features high noise immunity and very low static power consumption, making it exceptionally suitable for battery-operated and noise-sensitive environments. Housed in a 16-pin PDIP (Plastic Dual In-line Package), the device allows for easy cascading to create longer shift registers and includes a common active-high master reset that clears all stages to a low state. With its robust design, compatibility with a broad range of logic levels, and operation over a wide temperature range, the CD4015BCN is a fundamental building block for digital sequencing, timing, and data conversion circuits.
CD4015BCN shift register Applications
This dual shift register is widely used in applications requiring serial-to-parallel data conversion, such as reading multiple switch matrices or keypads, driving LED displays or seven-segment readouts, and interfacing serial data streams with parallel-input devices. It is also commonly employed in digital delay lines, sequence generators, simple data storage buffers, and as a building block in educational electronics and hobbyist projects for creating walking LED patterns, data logging systems, and control logic for multi-stage processes.
